Well, when I was 18 my boss at my terrible telesales job told me I couldn't use the title 'Ms' because it was only for divorced women.
At my right-on university I was informed that the title was only used by lesbians.
And when I got married everyone, even those who didn't have a problem with the fact that I'd kept my own surname, assumed I would now become a 'Mrs'.
I didn't actually beat these people over the head while shouting 'THE WHOLE POINT OF USING THE TITLE 'MS' IS NOT TO DISCLOSE A WOMAN'S MARITAL STATUS! WHY WOULD I CHANGE IT NOW?!', but I wanted to. And it seems I'm not alone.
A new petition on the government's e-petition website calls for Ms to be "the ONLY title for women." Granted, there are only 43 signatures at the time of writing - a far cry from the 100, 000 needed to force a debate in the House of Commons, but it's always nice to know you're not the only one. A similar campaign in France to make Madame the single title for women has more backing. This was started by the brilliantly named Chiennes de garde and Osez le Feminisme and it looks like their idea has crossed the channel.
It might seem like a trivial issue in some respects, but it's a source of annoyance that it's taken as a given that people should be able to tell my marital status from my name - my husband is incredibly important to me, but he has not changed my identity.
